Optimizing Network Routing by Deducing a QoS Metric Using Rough Sets
The routing within networks must satisfy the QoS metrics. In traditional data networks, routing is concerned on connectivity or cost. Routing protocols usually characterize the network with one or more metric(s). However, in order to support a wide range of QoS requirements, routing protocols need to have a more complex model. The network is characterized with multiple metrics such as bandwidth, delay, jitters, loss rate, authentication, security etc. This complex model necessitates a long time to proceed. The Rough Set Theory (RST) is applied to reduce these metrics successfully and decide the most effective ones. In this paper, RST is applied to reduce the online metrics that are reported by Routing Information Protocols (RIP).
